Abstract
Przedmiotem zgłoszenia jest sposób otrzymywania modyfikowanego haloizytu, który polega na tym, że haloizyt dysperguje się w rozpuszczalniku organicznym w proporcji masowej od 1:2 do 1:6, a do tak przygotowanej zawiesiny wprowadza się silny kwas mineralny w proporcji masowej do rozpuszczalnika organicznego od 0,01:1 do 0,05:1, a następnie związek modyfikujący o wzorze ogólnym, gdzie: R1 = łańcuch alkilowy o długości od 10 do 18 atomów węgla zawierających od 1 do 3 wiązań nienasyconych lub łańcuch alkilowy o długości od 6 do 10 atomów węgla zakończony grupą karboksylową lub pierścień aromatyczny podstawiony grupą karboksylową w pozycji para R2 = grupa benzylowa lub wodór, R3 = łańcuch alkilowy o długości od 6 do 10 atomów węgla zakończony grupą karboksylową lub pierścień aromatyczny podstawiony grupą karboksylową w pozycji para X- = jon chlorkowy, n = 1 - 6, wytworzony na bazie naturalnych kwasów tłuszczowych, w proporcji masowej do haloizytu od 0,1:1 do 0,5:1, proces modyfikacji prowadzi się w temperaturze 50 - 90°C przez 2 - 8 godzin, następnie wprowadza się środek suszący w proporcji masowej do haloizytu od 0,1:1 do 0,4:1, po czym rozpuszczalnik i środek suszący usuwa się, a osad modyfikowanego haloizytu suszy się i ewentualnie mieli się do postaci proszku.The subject of the application is a method of obtaining modified halloysite, which consists in the fact that halloysite is dispersed in an organic solvent in a mass ratio from 1: 2 to 1: 6, and a strong mineral acid in a mass ratio to an organic solvent from 0 to 2 is introduced into the suspension. , 01: 1 to 0.05: 1 followed by a modifying compound of the general formula, where: R1 = an alkyl chain with a length of 10 to 18 carbon atoms containing from 1 to 3 unsaturations or an alkyl chain with a length of 6 to 10 atoms carboxyl-terminated carbon or aromatic ring substituted with a carboxyl group in the para position R2 = benzyl group or hydrogen, R3 = an alkyl chain with a length of 6 to 10 carbon atoms terminated with a carboxyl group or an aromatic ring substituted with a carboxyl group in the para position X- = chloride ion, n = 1-6, produced on the basis of natural fatty acids, in mass ratio to halloyse here from 0.1: 1 to 0.5: 1, the modification process is carried out at a temperature of 50 - 90 ° C for 2 - 8 hours, then a drying agent is introduced in a mass ratio to halloysite from 0.1: 1 to 0, 4: 1, after which the solvent and desiccant are removed, and the modified halloysite precipitate is dried and eventually ground to a powder.
